Originally due last month, former Destiny's Child member Michelle Williams' third solo album, "Unexpected," will arrive Oct. 7 via Music World Music/Columbia.

As previously reported, the album steers away from Williams' gospel roots in favor contemporary pop and dance tracks, featuring collaborations with producers Jim Jonsin, Rico Lowe, Wanye Wilkins, Andrew Frampton and Stargate.

The first single, "We Break the Dawn," was co-written by Solange Knowles and has already spent time at No. 1 on the Billboard Hot Dance Airplay Chart.

Pulsating beats are front-and-center on "Lucky Girl," where Williams uses a vocoder, while "The Greatest" utilizes a martial drum pattern and a winding piano riff. Other tracks include the "Pump Up the Jam"-esque "Private Party" and the Heavyweights-produced "Thank U."

Williams is also showcasing her musical knowledge as a judge on MTV's newest music competition series, "MTV's Top Pop Group," which premiered yesterday (Sept. 11).
